If Joseph buys a T.V. At 35% off and it’s original costs $599.99 how much did he pay for the tv?

Monica [59]

Answer: He paid $\$389.9935$ for the T.V.

Step-by-step explanation:

We need to analize the information provided:

- The original cost of the T.V. was $599.99

- Joseph buys it at 35% off the original cost.

Let be "x" the amount Joseph paid for the T.V.

We can calculate "x" with the following expression:

$x=\$599.99-(\$599.99)(0.35)\\\\x=\$389.9935$

Therefore, he paid $\$389.9935$ for the T.V.
